abiotic factors‚ which are the nonliving things in the eco-column‚ include the water used in the aquatic habitat‚ soil used in the decomposition habitat‚ air‚ and some rocks that were used in the decomposition habitat. The biotic factors‚ which are the living things in the eco-column‚ include the grass and/or the terrestrial plants used in the terrestrial habitat‚ the fish (guppies) used in the aquatic habitat‚ and finally the worms that were used to feed the fishes once.
